Since Orville Wright first took to the skies over Kitty Hawk, North Carolina, experimental flight tests have been a relatively singular affair, with aviators taking their untried machines into the sky in search of good data and a great hangar story. But nowadays, cutting-edge testing of air and space machines has become somewhat more accessible. This week offers up another opportunity to witness an important milestone in experimental flight tests. NASA's Low-Density Supersonic Decelerator (LDSD) project will beam back to Earth live imagery from a supersonic, edge-of-atmosphere test of braking technology for Mars.

First off -- what will you see?

"You get to see all the same video I do, at the same time I do," said Mark Adler, project manager for LDSD at NASA's Jet Propulsion Laboratory in Pasadena, California. "This year's test is centered on how our newly-designed supersonic parachute will perform. We think we have a great design ready for the challenge, but the proof is in the pudding and the pudding will be made live for everyone to see."

So what exactly is that?

On launch day -- currently slated for June 2, but dependent on weather conditions -- the LDSD test vehicle will be carried aloft by a large weather balloon. NASA Television and JPL's Ustream channel will carry live commentary on the launch beginning at 1 p.m. EDT (10 a.m. PDT/7 a.m. HST).

For more than two hours, the balloon will carry the test vehicle to an altitude of 120,000 feet (37,000 meters). The tracking cameras NASA has employed for this year's test are expected to keep the balloon and test vehicle in their sights for about 30 minutes after launch. For this reason, at about 30 minutes after launch, the commentary will sign off temporarily.

Live video commentary is expected to return about 20 minutes before the LDSD test vehicle drops away from the balloon and the rocket-powered portion of the flight test begins. This second part of commentary could begin as soon as two hours after balloon launch or as late as about five hours after launch.Broadcast live streaming video on UstreamWhen the commentary resumes, viewers will see live, low-resolution images from high over the Pacific Ocean off the west coast of Kauai, Hawaii. Four cameras aboard the test vehicle will provide the LDSD mission team with different perspectives on the test. Two of the cameras provide views of the rim of the test vehicle and will show the performance of the Supersonic Inflatable Aerodynamic Decelerator (SIAD). A third camera will show the rocket motor firing, with Earth's horizon spinning in the background (the vehicle is spin-stabilized during the rocket flight), along with the deployment of the parachute's lanyards. The fourth camera looks directly up and will show the deployment of the ballute and supersonic parachute.

"What we will be looking most closely for is to see what happens on that fourth camera, when at Mach 2.35 our supersonic parachute is deployed," said Adler. "It may be hard to see because the transmitted video is low resolution, but we hope to be able to make it out."

During last year's flight, the test vehicle and the SIAD worked flawlessly. Its parachute, however -- the largest supersonic parachute ever flown -- did not perform as planned. Numerous improvements have been made to this year's chute - which will be the primary focus of this month's test.

The low-resolution imagery that is downlinked live and carried on NASA TV will be supplanted in the days after the test by ultra-high-resolution imagery from cameras carried aboard the test vehicle (seehttp://www.jpl.nasa.gov/news/news.php?feature=4604).

When and where do I tune in?

NASA commentary will be carried on NASA TV and on the Web at http://www.nasa.gov/nasatv andhttp://www.ustream.tv/nasajpl2. The test launch window for LDSD is from June 2 to June 12, and extends each day from approximately 1:30 p.m. to 3 p.m. EDT (10:30 to noon PDT / 7:30 to 9 a.m. HST).

On launch day, these same sources will provide updates on when commentary will resume with the drop and test flight of vehicle.

The LDSD crosscutting demonstration mission will test breakthrough technologies that will enable large payloads to be safely landed on the surface of Mars, and also will allow access to more of the planet's surface by enabling landings at higher-altitude sites. As NASA plans ambitious robotic science missions to Mars, laying the groundwork for even more complex human expeditions to come, the spacecraft needed to land safely on the Red Planet's surface will become larger and heavier in order to accommodate explorers' extended stays on the Martian surface.

The LDSD test vehicle was shipped to the U.S. Navy's Pacific Missile Range Facility (PMRF) in Kauai, Hawaii, aboard a U.S. Air Force C-17 cargo plane.

The Space Technology Mission Directorate at NASA Headquarters in Washington funds the LDSD mission, a cooperative effort led by JPL. The Technology Demonstration Mission program at NASA's Marshall Space Flight Center in Huntsville, Alabama, manages LDSD. NASA's Wallops Flight Facility on Wallops Island, Virginia, is coordinating support with PMRF and provides the balloon systems for the LDSD test.

The wave height is not conducive for safe recovery operations. The next launch attempt is Wednesday, June 3, no earlier than 1:30 a.m. EDT (7:30 a.m. HST).

The LDSD crosscutting technology demonstration mission will test breakthrough technologies that will enable larger payloads to be landed safely on the surface of Mars or other planetary bodies with atmospheres, including Earth. The technologies will not only enable landing of larger payloads on Mars, but they also will allow access to much more of the planet’s surface by enabling landings at higher altitude sites.

The project is led by NASA’s Jet Propulsion Laboratory in Pasadena, California. It’s supported by NASA’s Marshall Space Flight Center in Huntsville, Alabama, which manages the project as part of the Technology Demonstration Missions program for NASA’s Space Technology Mission Directorate in Washington.

Today’s launch (June 4) of the Low Density Supersonic Decelerator aboard a high-altitude balloon has been cancelled due to weather. A line of rain showers developed overnight moving towards the launch site, which result in unstable wind conditions near the surface that would prevent the launch of the balloon. NASA will evaluate the next available launch opportunity, Friday, June 5.bron:http://blogs.nasa.gov/ldsd/2015/06/04/nasa-scrubs-june-4-ldsd-launch/

NASA Go for June 8 LDSD LaunchPosted on June 7, 2015 at 7:12 pm by Kim Newton.The LDSD launch support team is go to report to stations tonight at 9 p.m. HST to begin preparations for a Monday, June 8, 7:30 a.m. HST (1:30 p.m. EDT) launch attempt from the U.S. Navy Pacific Missile Range Facility on Kauai, Hawaii. NASA Television and JPL’s Ustream channel will carry live coverage of the launch beginning at 7 a.m. HST (1 p.m. EDT).

The scientific balloon will begin inflation at 6:15 a.m. HST and after launch will take about three hours to reach its float altitude of 120,000 feet. About 45 minutes after the balloon reaches test altitude, the saucer-shaped LDSD test vehicle will be dropped and its powered flight will begin.

A solid-fueled rocket engine will kick in sending the test vehicle to the edge of the stratosphere, or about 180,000 feet, at a speed of Mach 4.

At about Mach 3, the test vehicle will deploy the supersonic inflatable aerodynamic decelerator (SIAD). The SIAD decelerates the vehicle to approximately Mach 2.4. The test vehicle will then deploy a supersonic parachute, which will carry the test vehicle to a controlled water impact.

The LDSD crosscutting technology demonstration mission will test two braking technologies that will enable larger payloads to be landed safely on the surface of Mars or other planetary bodies with atmospheres, including Earth.Bron:https://blogs.nasa.gov/ldsd/| Gewijzigd: 8 juni 2015, 10:35 uur, door Joyce.s

LDSD 2015 Launch Status Updates

LDSD Flight Complete; NASA to Hold Briefing to Discuss Status of ‘Flying Saucer’ TestPosted on June 8, 2015 at 7:10 pm by Kim Newton.NASA’s Low-Density Supersonic Decelerator (LDSD) project completed its second flight test when the saucer-shaped craft splashed down safely Monday in the Pacific Ocean off the coast of the Hawaiian island of Kauai. A post-flight media teleconference will be held at 1 p.m. EDT/7a.m., Tuesday, June 9 to review the test.

Two experimental decelerator technologies – a supersonic inflatable aerodynamic decelerator and a supersonic parachute – were tested. The supersonic inflatable aerodynamic decelerator deployed and inflated. The supersonic parachute also deployed; however, it did not perform as expected. Data were obtained on the performance of both innovative braking technologies, and the teams are beginning to study the data.
